PATENT 'IVIECHANISM FOR INTRODUCING TUBES INTO FURNACESJ SPECIFICATION forming part of Letters Patent No. 291,454, dated January 1, 1884. Application filed June 8, 1882. (No model.)

To all'whom it may concern.- y Be it known that I, EDWARD W. WoLFE, a citizen of the United States, and a resident of Reading, Pennsylvania, have invented certain Improvements in Mechanism for Introducing Tubes into Furnaces, of which the following is a specification. p

. The objectof my invention, which is fully describedhereinafter, is to afford facilities for introducing skelps into the furnaces of tubemills, and for returning tubes after they have passed through the rolls to the. furnace to be reheated prior to rerolling, the mechanism for performing these duties.

being such as to enableme to dispense with a number of ,the operatives heretofore required In the accompanying drawings, Figure 1, Sheet 1, is a general outline vicw,showing the character and purport of my invention; Fig. 2, a view of one end of the tube-furnace, looking in the direction of the arrow 1, Fig. 1; Fig. 8, a view of the opposite end of the furnace looking in the direction ofthe arrow 2; Fig.

4., Sheet 2, a side view of the traversing carriage and gearing for operating the same; Fig.

5, a plan view of Fig. l; Fig. 6, a transverse section on the line 1 2, and Fig. 7 vertical nace through theopening b in the end of the same. This combination of the furnace with a trough and raising and lowering mechanism forms the subject of a separate application which I am about to make for a patent. At

the opposite end of the furnace are the rolls and afixed trough or receiver, B, into which the newly-rolled tube is ,deposited, so as to be immediately returned to the furnace prior to being rerolled, as described in another separate application which I have made for apatent. A carriage, D, constructed at its lower end for attachmentto the push-rod x, has wheels adapted to a suspended track, E, and

at the opposite end of the furnace there is a As the mechanism for operating both ca r riages is the same, I will confine my description to the figures shown in Sheet 2. I

The suspended track E, previouslyreferred to, consists of two beams or rails, e e, preferably of iron, these beams being suspended by rods from the roof of the building and properly stayed.

The frame of the carriage D consists of two wrought-iron plates or hangers, (Z d, to which aresecured the two upper axles, f f, and two lower axles, f f each axle being provided with two flanged wheels, 9, so that there are four wheels above and four below the track-a plan which insures the maintenance of the 7 wheels on the said track, no matter what strains may be imparted to the carriage in operating To the lower end of the hangers d-d of the 80 carriage D is secured a block, h, Fig. 7, to which is swiveled the forked rod A sleeve, j, is confined to the push-rod w by and between a collar and nut on the same, and trunnions on the sleeve have their bearings in slots kin 8 5 the forked portion of the swiveled rod, as shown in Fig. 4, so that when the carriage moves in the direction of the arrow in that figure the rod :20 will be pushed before it.

detachable vertical pin (shown in Fig. 4) con- 0 fines the trunnions of the sleeve) within the slots of the forked portion of the swiveled rod, which, together with the pivoted sleeve, forms a universal-joint connection,-which is always to be preferred, as it permits the rod to be 5 tilted vertically, and to be moved laterally independently of the carriage. A drivingshaft, G, has its bearings in brackets m m, secured to one of the beams of the suspended trackjand two bevel-wheels, H H, are loose 011 this shaft, the teeth of both wheels being adapted to those of a similar bevel-wheel, I,

on a shaft, J, adapted to bearings K K, secured to thebeams of the track. A chain pulley, L, is secured to the shaft J, and near the opposite end of the track is a plain-flanged pulley, L, the shaft of which is adapted to bearings n n, andadrivingchain, l, is secured at one end to one end of the carriage, passes over the driving-pulley L, then from above the same to the pulley L, and round the latter to the opposite end of the carriage, where the opposite end of the chain is secured.

On the shaft G is a clutch, R, arranged to turn with but slide freely on the said shaft, one end of the clutch being constructed to engage in the hub of the bevel-wheel H, and the other to engage in the hub of the other bevelwheel. The clutch is controlled by two arms, 19 p, on a vertical shaft, T, Fig. 6, which has its bearings in a frame attached to the beams of the track.

To guides t on one of the beams is adapted a sliding rod, U, providedwith toes t, which are so situated that when the carriage approaches the limit of the movement by which a tube is pushed into the furnace awheel of thecarriage will "strike one of the toes and move the rod U, which is connected to an arm, 0, on the clutch-shaft T, thereby throwing the clutch out of gear and arresting the carriage, and when the latter is completing its movement in the contrary direction, so as to withdraw the push-rod from the furnace, a wheel of the carriage will strike another toe 011 the rod U, and again throwthe clutch out of gear. It will thus be seen that the carriage is automatically arrested as it reaches the limit of its movement in either direction, the throwing of the clutch into gear with one or other of the bevel-wheels H or H being effected by a handlever situated at any convenient point, and connected by suitable rods to the lever V, secured to the shaft T.

I claim as my invention- 1. The combination of the suspended track E, the carriage D, adapted thereto, the swiveling sleeve j and pusherbarre, the chain 1?, connected at both ends to the carriage, the pulley L, the shafts G J, bevel-wheels H H I, clutch It, and chain-pulley L on the shaft J, all substantially as set forth.

2. The combination of the suspended track, the carriage adapted thereto, the driving-shaft G, the bevel-wheels and clutch thereon, the shaft J, its chain-pulley L and bevel-wheel I, the sliding rod U, and mechanism whereby the said sliding rod, actuated by the carriage, is caused to operate the clutch and throw the said shaft J out of gear, all substantially as set forth.

3. The combination of the carriage, the forked rod Q3, swiveled thereto, the sleeve j, and the push-rod 9:. adapted to the sleeve and connected thereto, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 4
